The TextEncoder() constructor returns a newly created utf-8 TextEncoder object.
Syntax
encoder = new TextEncoder();
Parameters
TextEncoder()takes no parameters since Firefox 48 and Chrome 53
Note: Prior to Firefox 48 and Chrome 53, an encoding type label was accepted as a paramer to the TextEncoder object, since then both browers have removed support for any encoder type other than utf-8, to match the spec. Any type label passed into the TextEncoder constructor will now be ignored and a utf-8 TextEncoder will be created.
Exceptions
TextEncoder()throws no exceptions since Firefox 48 and Chrome 53
Note: Prior to Firefox 48 and Chrome 53 an exception would be thrown for an unknown encoding type.
